IMPROVEMENT IN MACHINES FOR WARPING YARNS.

Specification forming part of Letters Patent No. 192,571, dated July 3,1877; application filed February 6, 1877.

To all whom it may concern:

Be it known that I, JOHN GUMNOGK, of Great Falls, in the county ofStraiford and State of New Hampshire, have invented a new and usefulImprovement in Machine for Warping Yarn, which improvement is fully setforth in the following specification and accompanying drawing, in whichFigure 1 is a front elevation of a machine for warping yarn embodying myinvention, and Fig. 2 is a vertical section of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a device for cleaning theleaf, motes, 850., from the yarn while being wound onto or off fromsection-beams. The device might be applied to a slasher or similarmachine, but it is particularly intended for a warper.

The invention consists in the application of a brush or similar articleto the surface of the yarn upon the beam, as illustrated in the drawing.This brush is so applied as to press against the surface of the yarnupon the beam while the latter is in revolution. By this means eachfresh layer of the yarn is subjected, as it is Wound upon the beam, tothe action of the brush.

it represents the cylinder, b a frame in bearings, in which its journalsrest, and c the beam upon which the yarn is wound, all constructed asusual.

d represents the brush above mentioned, which presses upon the yarn onthe beam 0. Levers e, pivoted at e, extend back from each end of saidbrush, and, being provided with weights f at their farther ends, keepthe brush d continually pressed against the beam.

In practical operation the brush removes a large amount of objectionablematter from the yarn before sizing, which might by that process be madeto adhere to it until woven into the cloth. These motes are, some ofthem, of such a character, that, when sized, they cause the yarn tobreak in weaving; hence, the importance of a device for removing them inseason.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a warping-machine, the combination of the frame 1), weighted lever12, and brush (1, or

similar device connected thereto, the several parts being arranged asdescribed, whereby the leaf, motes, &c., are removed from the JOHN GUMNOGK.
